GoFuckYourself.com - Adult Webmaster Forum - Tech Form to sendmail dynamic email?

I have a form that I'm using that currently works well using the following sendmail.php file:

Quote:

<?php
if(isset($_POST['email'])) {

// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "[email protected]";
$email_subject = "Subject";

}

// validation expected data exists
if(!isset($_POST['name']) ||
!isset($_POST['email']) ||
!isset($_POST['phone']) ||
!isset($_POST['page']) ||
!isset($_POST['message'])) {
}

$name = $_POST['name']; // required
$phone = $_POST['phone']; // required
$email = $_POST['email']; // required
$page = $_POST['page']; // required
$message = $_POST['message']; // required

$email_message = "Form details below.\n\n";

function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}

$email_message .= "name: ".clean_string($name)."\n";
$email_message .= "phone: ".clean_string($phone)."\n";
$email_message .= "email: ".clean_string($email)."\n";
$email_message .= "page: ".clean_string($page)."\n";
$email_message .= "message: ".clean_string($message)."\n";

// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>

My question is this, how would I go about changing the above to dynamically change the $email_to field of the script?

What I'd like to be able to do is have a form on a page (with a unique id assigned to it) that will pull the user who uploaded the document to the databases registered email and, when the html form is filled out, it sends the email to them directly, without having to type their email address in the html form itself, does that make sense?

So if John submitted a document that is available on documents.php?id=123 it pulls his email from the registered user database (via the array if possible) and prefills the form (with a hidden field) so all my proofer has to do is fill out the message field and hit submit.

This is the current form HTML I'm using:

Quote:

<form action="https://www.domain.com/sendmail.php" method="post" class="wpcf7-form" novalidate="novalidate">
<input type="hidden" name="page" value="about"/>
<div style="display: none;">
</div>
<p>Your Name (required)<br/>
<span class="wpcf7-form-control-wrap your-name"><input type="text" name="name" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" aria-required="true" aria-invalid="false"/></span> </p>
<p>Your Phone (required)<br/>
<span class="wpcf7-form-control-wrap your-email"><input type="email" name="phone" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" aria-required="true" aria-invalid="false"/></span> </p>
<p>Your Email (required)<br/>
<span class="wpcf7-form-control-wrap your-email"><input type="email" name="email" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" aria-required="true" aria-invalid="false"/></span> </p>
<p>Your Message<br/>
<span class="wpcf7-form-control-wrap your-message"><textarea name="message" cols="40" rows="10" class="wpcf7-form-control wpcf7-textarea" aria-invalid="false"></textarea></span> </p>
<p> <br>
<input type="submit" value="Send" class="wpcf7-form-control wpcf7-submit"/></p>
<div class="wpcf7-response-output wpcf7-display-none"></div></form>

Is this even possible to do? :helpme
